ATTACHING HANDLEs To CUTLEHY;

Speccation of Letters Patent No. 26,478, dated December 20, 1859A f A i`To all whom it may concern."

y Be it known that I, MATTHEW CHAPMAN, of Greenfield, in the county ofFranklin and State of Massachusetts, have invented a new and ImprovedMode of Attaching Handles to Cutlery and to Implements or Tools ofVarious Kinds; and I do hereby declare that the following is a full,clear, and exact description of the same, reference be ing had to theannexed drawings, making a part of this specification, in which- Figurel, is a back viewof a table knife having its handle attached to itaccording to my invention, the handle being partly bisected. Fig. 2, isa detached side view of the tang of the blade and its nut.` Fig. 3, is adetached edge view of ditto.

Similar letters of reference indicate con responding parts in theseveral figures.

The object of this invention is to `oloviate the use of cement insecuring handles to cutlery and various tools, and to obtain a firm anddurable connection of the two parts by a very simple and economicalmeans. f

In the annexed drawings A, represents the blade of a table knife. B, isits tang. The tang is of the usual length, or taper or conical form andhas a screw thread a, formed on its lower end. This screw thread isflattened or filed off at two opposite points so as to form planesurfaces b, one of which is shown clearly in Fig. 3.

C, represents a `small metal cylinder which is iitted transversely inthe handleD, and passes entirely through it. This cylinder has a holemade through it transversely, said hole having an internal Screw threadto t the screw thread a, of the tang. The cylinder C, is adjusted in thehandle D, with its hole in a vertical position so as to receive thelower part of the `tang B, which is fitted in the handle D, as usual aproper hole being made longitudinally in the handle for its reception.The blade A, and tang B, are turned and the tan is conse uently drawnwithin the handle and the bolster c, of the blade is firmly pressed ordrawn on the end ofthe handle by the screw a, of the tang and thecylinder C, lwhichis` in fact a nut. `Whenthetang B,is snugly fitted inthe handle D, the ends `ofthe cyl?" :.z

hole made to bear against the flat `orplane@` sides of the screw a,thereby eifectuallyl pre-f venting the turning 1oit the tangwithinyit.`y By this arrangement the handle firmly and permanently secured to :thetang, the g cylinder or nut @,of course prevents the directwithdrawalof; the tang` from the handle, while the close adjustment `ofthe i cylinder to the plane "surfaces `3),",eiectually prevents theturnimgof` thetang'jandhthe consequent liability of its `becoming loose.l

I am aware that tangs havebeen secured in handles by rivets,but` theycan not bei firmly secured in that way `without the aid 1 of cement, itbeing impossible to prevent l f a play and rattle by the rivet alonerf`The" cement as is `wellknownis soonsoftened by washing the cutleryfinhot water and` oozes` 1I; 3 out between the bolster and handle leavingthe tang in a loose State. Bymy invention $1". the cutlery may bewashedin hot water t0 "75` least liable to `be injured in any way," and 1i ithe connection between the handle and the n will last as long as the`implement facilitate cleansing `without `being in; the

tane itseIf.

Having thus described my invention what I Claim 1S 116W and desire tosecure by Let` ters Patent, is,-` i v Securing handlesfto cutlery, andother tools or implements, by having a screwf i, thread a, formed on thetangs B, and` provided with plane longitudinal surfaces "b, inconnection with the cylinder or` nut C,l litted in the handleandhamineredor com-` pressed to tit the `screw a, and; its planesur-1.:` faces b, substantially as and` for` the pur-` pose set forth. y
